Just working on SVG export. There are more ways how to handle labels --
but no perfect one.
1) Use SVG fonts (embedded). These would be supplied with Therion
(converted from TeX fonts used in PDF output).
pros: the SVG map will be nearly identical to PDF
cons: large file (fonts are embedded)
SVG fonts are unhinted
hard to edit in drawing programs
hard to add new font
2) Use system fonts
pros: small file (fonts are not embedded)
full unicode support (if unicode fonts are installed)
cons: platform dependent
problems with precise alignment of labels
metapost can't calculate frames (e.g. for passage height) nor
clipping paths
3) Use system fonts but supply font metrics for metapost
pros: nice output with clipping paths, alignment etc.
cons: unportable
hard to generate metrics for the regular user
4) Use bitmaps as labels
cons: unscalable
would require additional convertor
uneditable
I'd like to get your comments, hints or suggestions, which one to prefer.
I'd say the 1st one.
Cheers,
Martin
